Gary Pendergast ffc4d6965c WPDB: Fall back to the connection charset when sanity checking strings. ...

If `DB_CHARSET` isn't defined (or is empty), `wpdb::$charset` will be empty, too. `wpdb::strip_invalid_text()` assumes that it isn't empty, however, so we need to fall back to the connection character set when we're running our sanity checks.

Fixes #34708.
